This paper discusses the properties of stylized U.S. ("U-type") and Japanese tournaments ("J-type"), which can both solve the unverifiability problem of labor contracts. Under a zero-profit condition, both tournament types will yield first-best efforts if workers are homogenous and risk neutral. This result will no longer hold for J-type tournaments if the employer has all the bargaining power. However, if workers are rik averse or one worker has a lead a J-type tournament may dominate a U-type tournament.
